The Mobile Robot Navigation System Design Based on GPS and GIS

Abstract

The paper develops an autonomous navigation system with Visual C++ 6.0, combining all-terrain and all-weather mobile robot platform with the high-precision dual-frequency RTK-GPS. The intelligent mobile robot achieves autonomous navigation control. Owing to the four-wheel drive, path tracking is better implemented; Owing to the use of high-precision GPS, position locating is more accurate; Owing to the multithreaded design of the program, real-time requirements of the navigation is better achieved; By the way of map matching of GIS, the path tracking is real-time and the navigation of the robot is more visual and intuitive. The result of experiment shows that this navigation system can meet the requirements of accuracy and real-time and complete the navigation task very well.
